Chapter 5 Configuring the Router’s Security
DMZ (Demilitarized Zone) Host
The DMZ host feature allows one device on the network to operate outside the
firewall. Designate a DMZ host:
• To use an Internet service, such as an online game or video-conferencing
program, not present in the Port Forwarding list and for which no port
range information is available.
• To expose one computer to all services without restriction or security.
M
Warning: A DMZ host is not protected by the firewall and may be
vulnerable to attack. Designating a DMZ host may also put other
computers in the local network at risk. When designating a DMZ
host, consider the security implications and protect it if necessary.
To designate a local computer as a DMZ host:
1. Select DMZ Host from the left side of any Security screen. The “ DMZ Host”
screen appears.
2. Click in the “ DMZ Host IP Address” check box, then enter the IP address of the
computer to be designated as a DMZ host. Note that only one network com-
puter can be a DMZ host at any time.
3. Click Apply.
Click in the “ DMZ Host IP Address” check box again to disable the DMZ host.
